Description: Entity Physical GUID (System or Module GUID)
What is mellanoxPhysicalEntityGUID?
This value is a globally unique identifier (GUID) assigned to a physical entity in a Mellanox switch or NIC, such as the chassis or a plug-in module. An administrator reads this to uniquely fingerprint hardware components, which is useful for asset tracking or confirming that a replacement module matches the one it replaced. For example, polling this OID for a swapped line card returns a new GUID string, confirming the physical module was actually changed.
